Cyclic Cohomology, Hopf Algebras and the Modular Theory
Alain Connes, Henri Moscovici
We associate canonically a cyclic module to any Hopf algebra endowed with a modular pair, consisting of a group-like element and a character, in involution. This provides the key c…

Cyclic cohomology and Hopf algebras
Alain Connes, Henri Moscovici
We show by a direct computation that, for any Hopf algebra with a modulus-like character, the formulas first introduced in [CM] in the context of characteristic classes for actions…
